ARROYO DIABLO. Arroyo Diablo, a canyon through which an intermittent stream runs, begins seven miles northwest of Small in southwestern Hudspeth County (at 31°22' N, 105°36' W) and runs southwest for twenty-five miles to its mouth on the Rio Grande, two miles southwest of McNary (at 31°14' N, 105°49' W). The stream has been dammed to form Diablo Reservoirs 1 and 2 for irrigation. It crosses flat to rolling terrain surfaced by sand and some clay loams that support scattered oak mottes, scrub brush, cacti, and grasses.
